i developed systems using mysql, many people advised me to study a new database system. I chose postgres because of the flexibility and many people recommended it to me. I uninstalled xampp from my local-machine. Now my question is what do i need to install aside from the windows installer for "postgresql-9.3.4-2-windows-x64" to start developing web based systems. I use php for back-end and html bootstrap for front-end. I want to use pgadmin III for managing database and where do i put my .php files to be able to run it locally?

Database structure help

June 19, 2014, 3:33 am

Hi,

I have been asked to create a database for my company. However I'm unsure which approach to take. Basically our products can have one or more "sub-systems" which each have different specifications. Most of the specification titles will be relevant to each sub-system.

It is yet to be decided whether this will be for the whole organisation as one central database or if it's just for a product selector for our website.

I've come up with two ideas:

To have two tables, one detailing the main product features e.g. size, model, part number which is linked ( One-to-many) to another table with every single specification for all sub-systems and then have a "Sub-System Type" field.

Or to have a table for each sub-system, linked to the main product table. Each sub-system table then has the relevant specification for that sub-system.

If you can help with deciding which is best and the advantages and disadvantages of each, I'd greatly appreciate it. Or perhaps there's a better way of doing it?

Thanks

Search button with text field

Hi,

I'm fairly new to Access / VBA and have been trying relentlessly to get a text box / search button on my Access form to pull up a specific record. Although the null command produces the correct error msgBox, it does not show any record if I enter a correct primary key term. Probably something really simple, but I am completely stuck and cannot find the solution anywhere.

Search button = SearchButton1
Search criteria text field = SearchText1
Primary key field = UniqueAEVRef

Code:

Private Sub SearchButton1_Click()
If IsNull(SearchField1) = False Then
Me.Recordset.FindFirst "[UniqueAEVRef]=" & SearchField1
Me!SearchField1 = Null
If Me.Recordset.NoMatch Then
MsgBox "No record found", vbOKOnly + vbInformation, "Sorry"
Me!SearchField1 = Null
End If
End If
End Sub

Please help!

Inconsistant Report

Hey everyone,

I've got some wonkiness with one of my reports and I can't quite figure out what's going on.

I have a navigation page on my main form. This navigation page has a subreport in it. I have two records in my table on this report. They used to show perfectly fine Then all of a sudden it start to only show the first one.

This is especially weird because I can pull up the report by itself and it will show both records. I can create a new form with a navigation page and a subreport and it will show both. I can remove the old subreport on the main page and add the same one back in and it will still only show one record...

Anyone seen this before? What control did I accidentally switch to do this? Thanks.

Highlight checkbox on got focus

Greetings,

I'm new to this forum, but have been lurking for awhile. I have a tabular form that has text boxes and checkboxes with each record in a row. I have all the text boxes set up with conditional formatting so that when the control has focus, the background colour changes to blue. However, I cannot use conditional formatting for the checkboxes. The users are older and find it hard to see where they are on the record when the focus goes to the checkboxes.

Is there some VBA code to highlight the actual checkbox when the user tabs into it?

I tried using a box behind the checkbox, but that affects all records. I need to just highlight the checkbox in the current record.

btw, I'm using Access 2010.

Thanks

ODBC Connection failed

Hi!

First of all excuse my bad english. I will try my best.

The Company which I work for offers a database program for the finacial sector. This program connects with a System-DSN entry with a MySQL database, which worked fine for a few years.

But a customer tried to install the program and send me this error: [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified

While I tried to reconstruct this error, i got the same Error but can't reverse it.I got it after i deinstalled the ODBC-Connector-Driver even though there was a active connection. I reinstalled the Connector and the workbench but there was still that error.

The Customer even reinstalled Windows but the Error remains. But i have to say that, because the customer is in the financial sector, there are made some changes to the system. For example at the permissions.

I tried to install a newer driver and a 32 Bit Driver too, but still no improvement.

The Systems both have Win 7 (64 Bit)

I hope you can help me!

I created an append query to insert data into another table based on the current entry of a specific field in the main form.
The data is inserted into a subform.
The problem I have is the following:
The first time the query runs (I acnnot runit via a button but in the query section only) everything works fine.
The second time it wirks but adds 6 instead of 2 entries. The next time 18 ... and so on. Any ideas?

INSERT INTO sh_information ( sh_information, sh_memo, sh_from, sh_schedule, sh_type, sh_name )
SELECT profile.profile_information, profile.profile_memo, profile.profile_from, profile.profile_schedule, profile.profile_type, q_togetthe_shname.sh_name
